3 Claims.

This invention relates to devices for removing liquid from gas lines. Inthe conveyance of gas through pipe lines,

there occurs an accumulation of moisture within the pipe, and thismoisture settles at various points in the pipe line where there aresags. To permit normal and natural flow of gas through the pipe line,therefore, it is necessary from time to time to remove the liquid whichsettles in the line as mentioned.

One object of this invention is the construction of a device of thecharacter mentioned, which will draw liquid within a gas line in athorough and eflicient manner.

Another object of the invention is the construction of a device of thecharacter described which may be operated by one man.

A still further object of the invention is the construction of a deviceof the character described which may be maintained and manipulatedwithout physical danger to the person handling the operation.

Still further objection of the invention and its advantages will appearin the description thereof taken in connection with the accompanyingdrawing.

In order that the invention may be readily understood and its particularadvantages fully appreciated, reference may be had to the accompanyingdrawing in which we have illustrated one form of its embodiment.However, it is to be understood that the invention is not confined tothe form of construction shown, and that various changes in the detailsof construction may be made within the scope of the claims, withoutdeparting from the invention.

In the drawing Figure 1 is a top view of the device.

Figure 2 is a side view thereof with portions broken away.

Referring now to the drawing in detail, the device consists of a tubel,the lower end 2 beveled as shown in Figure 2, and the top end 3 havinga valve 4 attached thereto.

A sleeve 5 has disposed in the upper end thereof a packing nut 6, and apacking nut 1 is disposed in the lower end thereof, the respectivepacking nuts 6 and I having holes centrally disposed therein and adaptedto receive the passage of the tube I through the respective packing nuts6 and l and the sleeve 5. A packing 8 is disposed within the sleeve 5between the packing nuts 6 and I and about the tube l.

The packing nut l is threaded at the lower end as shown in Figure 2, soas to engage with the 1925, Serial No. 22,374

neck 9 of the pipe Ill. The pipe l illustrates the conveyor pipe of thegas.

A cross-arm I8 is disposed on the sleeve 5, with a cross-pin II at oneend thereof and a reell2 at the opposite end thereof. Disposed at theupper end of the tube l and on one sidethereof is-the pulley [3. A cablel4 extends from the cross-pin ll over the pulley l3 and is attached tothe reel l2.

In operation, the packing nut I is attached to the neck 9 of the pipe[0, and the cable I4 is then wound on the reel l2, thereby lowering thetube I through the sleeve 5. In this manner, the lower end 2 of the tubel is brought to the bottom of the pipe Ill.

A chain l extends from the eye l6 at the upper end of the tube I, andthe lower end is adapted to engage with the hook ll on the crossarm l8.Thus, once the tube i is lowered into the pipe H], the chain 15 looks itfrom being forced upward from the pipe ID by the gas pressure.

On opening the valve 4, the gas within the pipe [0 will force the liquidaccumulated within the pipe l0 out through the tube I.

The construction, operation and advantages of my invention, will, it isbelieved, be understood and appreciated by those skilled in the art whenthe foregoing description is read in connection with the accompanyingdrawing. The degree of adjustment of the several members in .relation toeach other is such as to take care of any ordinary requirements; andwhile I have here shown and described certain novel features of myinvention, it is to be understood that various omissions, substitutionsand changes in the form and details of the device and its manner of usemay be made by those skilled in the art, and that I do not wish to berestricted to the precise structure disclosed, but hold myself entitledto make such changes therefrom as fairly fall within the scope of what Iclaim.

What I claim is, I

1. A device for withdrawing accumulated liquid from mains and the likecomprising a relatively fixed sleeve, said sleeve being provided at itsupper and lower ends with gland nuts, and being also provided at itslower end with means for attachment to a main, a tube slidable throughsaid sleeve and having an end adapted to be projected into the main, across arm extending laterally from said sleeve, a reel mounted on oneend of the cross arm, a guide pulley mounted on the upper end of thetube, a cable connected at one end with said cross arm at the endthereof remote from said reel, said cable being also trained over saidpulley and windable on said reel for forcing said tube through saidsleeve and into the main, and a valve on the upper end of said tube.

2. A device for withdrawing accumulated liquid from mains and the likecomprising a relatively fixed sleeve, said sleeve being provided at itsupper and lower ends with gland nuts, and being also provided at itslower end with means for attachment to a main, a tube slidable throughsaid sleeve and having an end adapted to be projected into the main, across arm extending laterally from said sleeve, a reel mounted on oneend of the cross arm, a guide pulley mounted on the upper end of thetube, a cable connected at oneend with said cross arm at the end thereofremote from said reel, said cable being also trained over said pulleyand windable on said reel for forcing said tube through said sleeve andinto the main, and a valve on the upper end of said tube, a flexiblemember secured at one end to said tube adjacent the upper end of saidtube, and inter-engaging means on the cross arm and said flexible memberfor securing said tube against movement axially through said sleeve inone direction.

3. A device for withdrawing accumulated liquid from mains and the likecomprising a rela tively fixed sleeve, said sleeve being provided at itsupper and lower ends with gland nuts, and being also provided at itslower end with means for attachment to a main, a tube slidable throughsaid sleeve and having an end adapted to be projected into the main, across arm extending laterally from said sleeve, a reel mounted on oneend of the cross arm, a guide pulley mounted on the upper end of thetube, a cable connected at one end with said cross arm at the endthereof remote from said reel, said cable being also trained over saidpulley and windable on said reel for forcing said tube through saidsleeve and into the main, and a valve on the upper end of said tube, achain secured at one end to the tube adjacent the upper end of thelatter, and a hook on said cross arm with which the free end of saidchain is engageable for locking the tube,

against being forced upwardly through said sleeve and outwardly withrespect to said main,
